APPARATUS FOR KILLING RODENTS.

SPECIFICATION forming part of Letters Patent No. 263,209, dated August22, 1882.

Application filed May 9, 1882.

.To all whom it may concern:

Be it known that I, AUSTIN D. PALMER, o

Abilene, in the county of Taylor and State of Texas, have invented a newand Improved Apparatus for Killing Rodents, of which the following is afull, clear, and exact description.

The object of my invention is to furnish an apparatus that may be usedeffectively for the destruction of all animals that burrow in theground; and it consists in a furnace for the generation of sulphurousodors or other suffocating gases and a pump for forcing the gases intothe burrows of theanimals, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specificatiomin which similar letters of reference indicatecorresponding parts in both the figures.

Figure l is a sectional elevation of the ap-. paratus as arranged foruse. Fig. 2 is a horizontal section of the furnace.

Ais the furnace, which consists of an inner cylinder, a, closed at thebottom and perforated in the upper portions, and an outer inclosingcase,b, which has an open bottoin'and is provided at the top with a removablecap, 0, that gives access to the interior of the furnace. d is a tubefrom the lower part of the inner cylinder, a, extending through the caseb, and provided with a flexible tube, 6, for connection with the pump.The furnace is also provided with a handle, f, for convenience incarrying it.

B is an air-pump, that may be of any suitable construction, providedwith a piston-rod, g, and having its outlet-pipe h connected with theflexible tube 0 of the furnace. The pump (No model.)

is mounted upon a suitable base and provided with a strap, 1', for usein carrying the pump from place to place.

, In the operation of the apparatus the furnace is to be placed over theoutlet of the burrow and the soil packed tightly around the lower end ofthe inclosing-case b, so as to exclude the'air. Sulphur or othersuitable material is placed in the furnace, together with fire-brands,and the pump then operated to force the air into the furnace through theflexible tube. This operation causes the quick combustion of the sulphurand the odors are forced into the burrow, so that the animals thereinare quickly suffocated. I

The apparatus may be made of any suitable size according to therequirements, and may be used for the extermination of prairie dogs andother animals of the rodent species. The material used is preferablysheet metal.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In-an apparatus for exterminatin-g rodents, the furnace consisting ofthe outer bottomless vessel, A, the inner serially-perforated vessel, a,with its bottom arranged above the plane of the lower edge of thevessel'A, and having a cover, 0, and the pipe or pipes d 0, connectingthe same with a force-pump, substantially as I shown and described, andfor the purpose set forth.
